Synopsis


xine-lib is vulnerable to multiple buffer overflows when processing media streams.

Background


xine-lib is the core library package for the xine media player, and other players such as Amarok, Codeine/Dragon Player and Kaffeine.

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/xine-lib < 1.1.13 >= 1.1.13

Description


Multiple vulnerabilities have been discovered in xine-lib:

  • Alin Rad Pop of Secunia reported an array indexing vulnerability in the sdpplin_parse() function in the file input/libreal/sdpplin.c when processing streams from RTSP servers that contain a large "streamid" SDP parameter (CVE-2008-0073).
  • Luigi Auriemma reported multiple integer overflows that result in heap-based buffer overflows when processing ".FLV", ".MOV" ".RM", ".MVE", ".MKV", and ".CAK" files (CVE-2008-1482).
  • Guido Landi reported a stack-based buffer overflow in the demux_nsf_send_chunk() function when handling titles within NES Music (.NSF) files (CVE-2008-1878).

Impact


A remote attacker could entice a user to play a specially crafted video file or stream with a player using xine-lib, potentially resulting in the execution of arbitrary code with the privileges of the user running the player.

Workaround


There is no known workaround at this time.

Resolution


All xine-lib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.13"
